It takes me an hour to get an mSD card up to my 'clean point'. Everytime I want to step back, it is a lot of steps. So I went looking for my old notes on making a .img from a mSD with dd (I think) and coming up empty. Can some one point me to where I can find how to do this? I am doing something wrong with postfixadmin. And I want to step back and try again...
